Reconstruction of frontal bone using specific implant polyether-ether-ketone.
Defects on the craniofacial complex may result in aesthetic defects, functional damage, and psychologic consequences. Previously, surgeons showed no interest in reconstructing the operated area, but in the treatment of the problem, leaving bone contour is a secondary issue. Nowadays, area reconstruction with post-reestablishment of contour and local shape has become one of the surgeon's priorit...
متن کاملLocal deformation behavior of surface porous polyether-ether-ketone.
Surface porous polyether-ether-ketone has the ability to maintain the tensile monotonic and cyclic strength necessary for many load bearing orthopedic applications while providing a surface that facilitates bone ingrowth; however, the relevant deformation behavior of the pore architecture in response to various loading conditions is not yet fully characterized or understood. The focus of this s...
متن کاملIn Vitro Evaluation of Bioactivity of Chemically Deposited Hydroxyapatite on Polyether Ether Ketone
Polyether ether ketone (PEEK) is considered the best alternative material for titanium for spinal fusion cage implants due to its low elasticity modulus and radiolucent property. The main problem of PEEK is its bioinert properties. Coating with hydroxyapatite (HA) showed very good improvement in bioactivity of the PEEK implants. However the existing methods for deposition of HA have some disadv...
متن کاملMean strain effects on cyclic deformation and fatigue behavior of polyether ether ketone (PEEK)
The fatigue behavior of polyether ether ketone (PEEK) thermoplastic was investigated under uniaxial strain-controlled cyclic loading condition with various mean strains (Rε 1⁄4 0, 0.2, and 0.25). The mean stress responses of PEEK from all mean strain fatigue tests were found to be fully-relaxed. As a result, minimum mean strain effect on fatigue behavior of PEEK was observed. Fractography analy...
متن کاملAn Automated Solid Phase Extraction Polyether-ether Ketone Microfluidic Device: Influence of Sorbent Packing
The work presented here aims at developing a microfluidic device for automated sample enrichment of water samples. The device is optimized for the analysis of small organic pollutants by biosensing and environmental monitoring applications. Miniaturization and automation of solid phase extraction with our device enabled us to reduce the volume of sample and of eluent significantly, resulting in...
